If you don't need this information now, chances are you will in the future.

Cleaning the optical path of any camera is one of those necessary evils. Even the simplest point and shoot camera, be it digital or film, will eventually need the tiny front element of its lens cleaned.

But when it comes to an SLR, especially a DSLR, things get a lot trickier. You can't just spit on the front of the lens and rub it with your elbow while wearing a long sleeve shirt.

All digital cameras have a "sensor", but since it is buried deep inside you're the camera body and inaccessible, it's of no concern, unless it's a DSLR. These cameras allow for interchangeable lenses and because of that the sensor cannot be sealed off and protected from dust.

I located an excellent and thorough tutorial that outlines several methods for cleaning the sensor in a DSLR. As is stated in the introduction, this is not a task to be undertaken lightly, so please understand that you do this at your own risk. I can't recommend or guarantee any method, so read the entire tutorial carefully and then decide if you want to proceed. Here's the link.

This article is dedicated to cleaning the sensors in Nikon digital cameras. Again, the same caution applies.

Delkin has introduced a kit that supposedly makes the task easier and safer.

I have no connection to the company, nor have I used the product. I simply want to pass this information along since many DSLR owners are now experiencing the problem of dust buildup on their cameras sensors, and it's advisable to keep up with products that address the issue. I'm sure other companies will be introducing their own versions soon.

For your convenience here's the Delkin website.
